Who's fought Silverado/ Sierra brake problems? and won?

We had a fleet of 90's and early 00's gm s10 and astro's at a place I used to work.

Some were downright scary with the brakes.

With my particular s10, any time you had your foot on the brake pedal, even with just "I might need to stop" pressure, and went over any change in pavement, pothole, patch, gravel, etc, the ABS would kick on and the pedal would drop almost to the floor.

Truck was in to fleet maint six times for brakes and they never found or fixed anything, including the guy that had it before me was involved in an at fault accident attributed to the brakes!

...on the other side- it was a short cab with a 4.3, and would bark second gear!
